Google Earth和Sketch Up环境下三维场景建立方法研究

Studies on the Implementation Methods of 3D Scene Based on Google Earth and Sketch Up

三维场景是直观有效表达客观世界的方法之一,在建筑、交通、城市规划和GIS领域均有广泛的应用。本文以石家庄经济学院为例,介绍了采用Sketch Up作为建模工具,以Google Earth为模型浏览平台的三维场景建立方法,阐述了Sketch Up建模的方法和步骤、模型上传与发布等方面的内容。最后得出结论:该方法较其他三维场景建立方法具有简洁、易学、网络共享等优点。

3D Scene is an intuitive and effective method of expressing the real world. It has been widely used in building, transportation, city planning and GIS area. For the Shijiazhuang University of Economic case, this arti- cle introduces the implementation methods of 3D scene which has used the Sketch Up as modeling tool, and the Google Earth as the model browser. It also expounds the method and step of modeling using Sketch Up, models u- ploading and releasing. At last, the paper gives the conclusion that this method has the advantages of briefness and internet tethering.
